'comb-at' by Lorenzo Damiani.(red combs) 'combmando' by studiobo
I love these knife combs designs. The red knife comb called 'comb-at' by Italian designer Lorenzo Damiani. And Thailand based studio studiobo also created 'combmando'(below pic), which looks like a real knife. These combs for personal defense, you can keep in your handbag, they are lightweight and Cool!
